It’s worth remembering that the benchmark efficiency measure for the HEPA filters used in the air supply to hospital operating theatres is 0.3 microns.

Which means if Ebola or norovirus cells were floating around, there’s nothing there to stop them getting through.

Aha, right! Neither of these two is airborne in transmission – infection is by direct contact. No immediate problem.

But spread from one place to another? Airborne always!

Smaller travels further

Because if Sahara dust can travel 2,000 miles and get dumped on your car, what about germs that are less than 2% smaller?

Which means, if the winds blow in the right direction, that Ebola could already be here. Floating around, waiting for an opportunity. Norovirus certainly is.

And you’ve seen yourself how fine dust floats even in still air, seemingly unaffected by gravity. At 1,000 times smaller, germs like norovirus or Ebola might never settle – the air around them is too dense for gravity to work.

OK, so here comes a human body, pushing through the air, walking down the street. Whatever germs there are, catch and stick like always – on skin, clothing everywhere.

Single germ cells on the skin’s acid mantle, not a problem. Our immune systems are too rugged, too smart.

Catching germs

But winds blow and air wafts – people, cars and animals pass through it, heating systems vent into it. Those germs don’t stay in one place, they move around – fetch up on other surfaces – walls, doors, through windows, wherever.

And a human hand, wiping across one of these in a grab for a door handle, might scrape 10 or 20 together in a ridge that stays sticking to a finger. Next thing, like we always do 2,000 – 3,000 times a day, that finger wipes an eye, wiggling round to remove street dust.

So what’s the prognosis, Doc?

Infection alert

20 Ebola germ cells clumped together on the moist tissue round the eye – will there be an infection or not? (Tweet this) And if there is, can you imagine the hoo-hah about how it happened?

You can’t see germs. You can’t take chances either. Which is exactly why hospitals are starting to use the Hypersteriliser.

Because the Hypersteriliser’s super-fine mist of ionised hydrogen peroxide takes out ALL viruses and bacteria to a Sterility Assurance Level of Log 6. Hydroxyl radicals, reactive oxygen species – and even ozone – rip them apart by oxidising them. No Ebola, no norovirus, no nothing.
